Found this one while picking through a roll. SOOOO hard to get photos (Thats why I included three shots). Seems to exhibit a lot of the characteristics of the 89 DDO. Any takers? Thanks!
Yours doesn't seem to have the thickness in the date. Maybe I'm missing something? http://coppercoins.com/lincoln/diestate.php?date=1989&die_id=1989d1do001&die_state=mds
